What is the primary characteristic of CS?

The primary characteristic of CS, which is commonly known as tear gas, is that it is a man-made irritant with a pungent odor. This compound is specifically engineered for its effects on the eyes and respiratory system, causing irritation and discomfort. The synthetic nature of CS is crucial as it allows for controlled production, ensuring its effects can be replicated consistently for various applications, primarily in crowd control and law enforcement scenarios.

In contrast, the other characteristics presented do not accurately represent CS. For example, labeling it as a natural extract would imply that it is derived from a natural source, which is not the case. Additionally, while it can be classified as an organic compound in chemical terms, this description is too broad and does not capture the specific properties that define CS. The mention of a floral scent is also incorrect, as CS is known for its harsh, acrid smell rather than anything pleasant or floral.
